Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a coupling capable of accurately forming a shape of a main body part in a coupling when forming the coupling and its forming method, a droplet discharge head and a droplet discharge apparatus. SOLUTION: The coupling 1 consisting of a jointing part 2 jointing with a tube and a main body 3 is formed by molding resin. The jointing part 2 has a protruding part 7 and a gate part 22 is provided in an inclined surface 7a of the protruding part 7 when molding it and a runner part 21 and the coupling 1 are connected by the gate part 22. When cutting the gate part 22, the gate part 22 is cut by a cutting blade tool 24a and a cutting blade tool 24b so that the protruding part 7 is formed. COPYRIGHT: (C)2008,JPO&INPIT
